How to Convert JPG to PDF on Your Phone (No App Needed)
Updated 18 October 2026 · 4 min read
Turn photos, scans and screenshots into one PDF on Android or iPhone without installing an app — free and private.
When you need a PDF instead of photos
Colleges, offices and portals often ask for one PDF instead of many images — for assignments, receipts, ID proofs or certificates. A single PDF is easier to email and keeps the page order.
Steps on Android or iPhone
Open SolveIt in your phone browser (Chrome or Safari):
- Open JPG to PDF and tap the upload area.
- Select one or more photos from your gallery.
- Arrange them in the right order and choose the page size (A4 is standard).
- Tap Convert and download the PDF.
Tips for clean pages
A few small things make the PDF look professional:
- Shoot photos from directly above in good light.
- Crop the edges of each page before converting.
- If the PDF is too large, run it through Compress PDF afterwards — or use the Scan to PDF workflow, which does both in one go.
Privacy
Your photos are converted on your phone itself. Nothing is uploaded, so it is safe for personal documents.
